It ended up with a mock of some faces in a almost-top-down view.
As mentioned in the post, a night of sleep changed my vision (as often).
I never really experimented with isometric views, so I said: why not? Google, isometric art tutorial, some sketch, some try in Tiled and now I've got another mock with poor (but, again, consistent) art that I want to share here.
I think it looks quite better than the previous one, more immersive... or not?
